1. Electro-hydraulic hammer current situation

 Electro-hydraulic hammer development benefits from its huge energy-saving effect. In addition to the advantages of hydraulic pneumatic hammer in transmission principle, it also has considerable advantages in structural control.

通过传感器对液压油的清洁度,温度,压力,液位等进行监察,一旦出现不符合系统运转条件的现象即自动报警,并可实现自我保护,停锤甚至停机.

  Through the sensor to monitor the cleanliness, temperature, pressure, liquid level of hydraulic oil, once the phenomenon does not meet the operating conditions of the system, it will automatically alarm, and can realize self-protection, stop hammer or even stop the machine.

采用自动控制系统,使每锤的打击能量及每个工件的打击次数均能按需得到控制,使得打击系统的振动情况大为改善,打击噪音大大降低,同时降低了对操作者的技术要求,锻件的精度也相对稳定,设备运行的可靠性及模具的寿命均得到提高.

  By using automatic control system, the striking energy of each hammer and the number of striking times of each workpiece can be controlled on demand. The vibration of the striking system is greatly improved and the striking noise is greatly reduced. At the same time, the technical requirements for operators are reduced. The precision of forgings is relatively stable. The reliability of equipment operation and the service life of dies are improved.

据不完全统计,我国拥有可进行改造的电液锤近2500台,节能效果在90%以上已被证明,锻造行业通过对其进行及节能改造,不失为一个步出高能耗低效益困境的有效途径.

  According to incomplete statistics, there are nearly 2500 sets of electro-hydraulic hammers that can be transformed in China, and the energy-saving effect is more than 90%. It has been proved that the forging industry can step out of the dilemma of high energy consumption and low benefit by carrying out energy-saving transformation.

2. Working principle of electro hydraulic hammer

 The rod chamber of the working cylinder always passes through constant pressure oil. When the pressure oil is fed into the non rod chamber, the rod cavity and the rod free cavity are connected at the same time to realize differential, and the hammer head drops rapidly under the action of itself and oil pressure to realize striking. After the impact, the rodless chamber is connected with the oil return port, and the path to the rod chamber is cut off at the same time. The hammer head returns quickly under the action of the pressure oil in the rod chamber.

采用此原理的液压锤,既克服了进油打击方式液气锤有杆腔压缩气体少量泄漏即影响锤头不能正常回程及回程速度,位置难以得到控制的缺陷,又克服了放油打击方式液气锤闷模时间长,回弹连击,回程速度慢,打击频率低等缺点.

The hydraulic hammer based on this principle not only overcomes the defects of small amount of compressed gas leakage in rod cavity of hydro pneumatic hammer in oil feeding striking mode, which affects the normal return of hammer head and the difficulty to control the return speed and position of hammer head, but also overcomes the disadvantages of long mold clamping time, springback continuous strike, slow return speed and low strike frequency.
